Welcome to #teamhaem! The rules are simple… we post a case on this site and then people comment on Twitter by replying to @teamhaem and using #teamhaem so everyone else can follow the conversation. Join in!

…which probably means that a lot of Teamhaemers are particularly busy just now – Christmas parties, last minute shopping and so on. But we don’t want to leave you uneducated over the Christmas season! So, for the motivated, and for those from countries that don’t celebrate Christmas, we have constructed a couple of short cases. Both are more of diagnostic interest so join in from the outset – they will move quickly!

The first case starts with a blood film. There are no clinical details.

What can you see? If you’re a lab professional use the official terms but of you’re not still have a go – what looks odd? Get descriptive…

Please reply on Twitter and always include #teamhaem to allow others to follow your comments. Please join in the debate and learn about haematological problems along the way. The case will continue to evolve over the coming week so keep checking #teamhaem for more information.

All contributions are valid – there is no such thing as a stupid suggestion – we’re all learning together.
